High Speed CMOS Logic
Quad 2-Input EXCLUSIVE NOR Gate
Description
The Harris CD74HC7266 contains four independent
Exclusive NOR gates in one package. They provide the
system designer with a means for implementation of the
EXCLUSIVE NOR function.
This device is functionally the same as the TTL226. They
differ in that the HC7266 has active high and low outputs
whereas the 226 has open collector outputs.
